Today, we’re blowing the lid off the Erupter Perfect Fuzz, from EarthQuaker Devices. The Erupter was designed as the ultimate classic fuzz, using every last trick in the book to achieve perfection. The idea behind this perfection is that the Erupter had to retain plenty of low end, plays nice with wahs at any point in the signal chain, and screams with any guitar and pickup combination that ever existed. To achieve this, the Erupter features a transformer-based pickup simulator to ensure no tone loss across any guitar in your collection. A buffered input section means the Erupter still earns its name when used with a wah pedal, tearing through any impedance mismatches that classic fuzzes are famous for. At the component level, the Erupter contains a full palette of mojo-filled components, including two specially-matched NOS globe-top transistors, new-stock half-watt carbon composition resistors, Sprague and BC capacitors. The Erupter contains only one knob for Bias, with the fuzz level internally dimed and the Volume pre-set to a universal unity level. The Bias control is center-detented, and is capable of delivering an incredible range of vintage fuzz tones. The lower half of the control dredges up spongy, sludgy misbiased fuzz tones that drenches your tone with blooming attack that gives way to a sputter sag that gates without any weird Velcro-like decay. The right side of the detent shovels loads of harmonics onto the signal for a burly, creamy fuzz that tightens up as you increase the knob, all while retaining the optimal volume and fuzz settings. And just like all EarthQuaker’s Devices, the Erupter is forged one at a time within the subterranean dwarven foundry of Akron, Ohio.
